IMPROVEMENT lN DEVICES FOR ATTACHING HUBS TO AXLES.

Specification forming part of Letters Patent No. 195,245, datedSeptember 18. 1877; application filed July 9, 1877.

To all whom it may concern Be it known that we, FRANK H. ALLEN and JAMESLATHROP, both of the city of Norwich, county of New London and State ofConnecticut, have invented certain new and useful Improvements in theMethod of Securing Carriage Wheels to Axles, a full and cleardescription of which is contained in the following specification,reference being bad to the annexed drawings.

This invention is an improvement on a patent of the United Statesgranted to the subscribers April 24, 1877, No. 190,052, and in thefollowing description we wish it clearly under stood that we do notagain claim the tube (B, Fig. 2) on which the wheel rotates.

Our improvement relates only to the method of securing the said tube tothe axle and to the oil-reservoir within the tube.

In the improvement which is the subject of this specification the axlereceives all possible strength at the flange or collar C, inasmuch as nocuts, slots, or holes are necessary at that place.

In the accompanying drawings, Figure 1 represents an .axle constructedwith our improvements, showing at b 1) sections of a flange, thediameter of which is equal to the outside diameter of the tube B.

The outer end of the axle A is slotted transversely, and has also a holeof suitable size to receive a spiral spring, and a latch orspring-catch. (Shown at D in the same diagrain.)

The latch d is held in place by a pin pass ing through the axle andthrough a slot in the latch. This slot in the latch 01 allows sufficientoutward and inward movement to accomplish the desired result.

The axle A, Fig. l, is reduced in size at h,

to receive a sleeve of felt or other porous material, in which is heldin reserve a large quantity of oil, melted tallow, or other suitableaxle-grease. This reserve of axle-grease is designed to keep the tube B0001.

Should the tube B become heated and dry, the heat will draw from thereserve in the porous reservoir sufficient grease to lubricate the tube,and thus prevent the wheel from sticking and grinding.

Fig. 2 shows the tube B, which remains nearly the same as in our formerpatent of April 24, 1877.

This tube has been shortened slightly, and has also received atransverse slot across the outer end, as shown at e, Figs. 1 and 2, intowhich the catch d springs when the tube is slipped on the axle.

To operate this device, place a flat key or wrench in the slot 0, givingpressure enough to throw the catch at inward, thereby releasing the lugsg, and allowing the tube to be withdrawn from the axle. After cleansingand lubricating, return the wheel and tube to their place on the axle,pass the lugs g through the openings a, giving the tube about onetourthturn to the left, when the lugs y will engage with the projections b b.At the same instant the catch (1 will spring forward into the slot e,effectually locking the tube B to the axle.

The flange i on the tube B prevents the wheel from slipping off thetube.

All the locking and working parts in this device are inclosed in thetube B, where no dust, snow, or gravel can get to them.

We do not now claim the tube B; but we do claim- 1. In combination .withthe axle A and tube B, the spring-catch 01, arranged and operated as andfor the purpose specified.

2. In combination with the axle A and tube B, the porous reservoir h h,as arranged and for the purpose specified.

3. In combination with the axle A, tube B, and springeatch d, theprojections b b, as and for the purpose specified.

In witness whereof we have hereunto set our hands and seals this 21stday of June, A. D. 187 7.
